38 the DSP supports filtering in hardware, however, since the "muxstream"
39 is a bit braindead (no matching channel masks or no matching filter mask),
40 we won't support this - yet. it doesn't event support negative filters,
41 so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
42 parse TS data. USB bandwith will be a problem when having large
43 datastreams, especially for dvb-net, but hey, that's not my problem.
45 TTUSB_DISEQC, TTUSB_TONE:
46 let the STC do the diseqc/tone stuff. this isn't supported at least with
47 my TTUSB, so let it undef'd unless you want to implement another
48 frontend. never tested.
51 define it to > 3 for really hardcore debugging. you probably don't want
52 this unless the device doesn't load at all. > 2 for bandwidth statistics.
